Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a DC motor drive controller in which increase in size and cost of a heat dissipation component, and short life of a switching element can be suppressed by suppressing high heat generation from one component, i.e. the switching element, and to provide a pump unit. SOLUTION: The DC motor drive controller 20 is performing PWM peak current control, i.e. simultaneous control of PWM control and peak current control, in a section where PWM control was performed conventionally. Since the number of switching times of a switching means 23 is decreased, high heat generation from the switching element 23 is suppressed. COPYRIGHT: (C)2007,JPO&INPIT
